Each year, the magazine, in partnership with Trucost and Sustainalytics, assesses the 500 largest U.S. and global companies and assigns each a “Green Score,” derived from three components:
- an Environmental Impact Score (45% of the total) compiled by Trucost, involving more than 700 metrics — a comprehensive, quantitative, and standardized measurement of the overall environmental impact of a company’s global operations;
- an Environmental Management Score (45%) compiled by Sustainalytics, an assessment of how a company manages its environmental footprint, including its environmental policies, programs, targets and initiatives of both its own operations and its suppliers and contractors, as well as the impact of its products and services; and
- an Environmental Disclosure Score (10%), evaluating the quality of company sustainability reporting and involvement in key transparency initiatives such as the Global Reporting Initiative and Carbon Disclosure Project.
